Abstract (en)

[origin: WO2014090845A1] Tyre tread comprising a central part (I) made from at least one first rubber compound and comprising at least one circumferential rib (121-123) formed of a plurality of blocks (1210) separated by sipes; a first and a second lateral part (II and III) made of at least one second and one third rubber compound, and comprising at least one circumferential rib (131,141) formed by a plurality of blocks (1310,1410), separated by sipes, wherein the said at least one second and third rubber compounds have a value of tanδ < 0.25 - at a temperature of 23°C, a frequency of 10Hz and an elongation of 10% -, wherein the complex modulus G* (T) of said at least one first rubber compound is greater than the complex moduli G* (T) of said at least one second and third rubber compounds for all temperatures 0° ≤ T ≤ 60°C.
